Modifier and Type	Method	Description
abstract ManagedIdEntitiesImpl<E>	clone()	Each map wrapper should be cloneable where the contents are references of the original where possible but the underlying map itself is newly created

void	recreateIds(boolean resetManagedIdClass)	Recreate the ids for all registered entities with or without resetting
void	reset()	When reset it called, it not only clears the entries, but also resets the managedids, such that when the container is reused the managed ids start from zero again.

Field Detail

managedIdClass

protected final Class<? extends ManagedId> managedIdClass

the class signature used for generating the managed id within the group defined by the token

Constructor Detail

ManagedIdEntitiesImpl

protected ManagedIdEntitiesImpl(Function<E,Long> valueToKey,
                                Class<? extends ManagedId> managedIdClass)

Constructor

Parameters:

valueToKey - the mapping from key to value of the graph entity

managedIdClass - should reflect the class signature used for generating the managed id of this class when creating it via the factory of this container

ManagedIdEntitiesImpl

protected ManagedIdEntitiesImpl(ManagedIdEntitiesImpl<E> other)

copy constructor

Parameters:

other - to copy

Method Detail

updateIdMapping

protected void updateIdMapping()

updates the container keys based on currently presiding ids. Only to be used when an external force has changed already registered edges' their ids

getManagedIdClass

public Class<? extends ManagedId> getManagedIdClass()

Collect the class identifier used for the managed ids within the id group for instances of this class used in this container

Specified by:

getManagedIdClass in interface ManagedIdEntities<E extends ManagedId>

Returns:

managedIdClass for instances this factory creates

recreateIds

public void recreateIds(boolean resetManagedIdClass)

Recreate the ids for all registered entities with or without resetting

Specified by:

recreateIds in interface ManagedIdEntities<E extends ManagedId>

Parameters:

resetManagedIdClass - when true we reset the managedId's counter to zero (via its id class) before recreating the ids, otherwise we simply recreate the managed id by starting with the next available id without resetting

reset

public void reset()

When reset it called, it not only clears the entries, but also resets the managedids, such that when the container is reused the managed ids start from zero again. If any entries are managedEntities themselves or contain managed entities themselves, they are reset as well

Specified by:

reset in interface ManagedIdEntities<E extends ManagedId>

clone

public abstract ManagedIdEntitiesImpl<E> clone()

Each map wrapper should be cloneable where the contents are references of the original where possible but the underlying map itself is newly created

Specified by:

clone in interface ManagedIdEntities<E extends ManagedId>

Specified by:

clone in interface MapWrapper<Long,E extends ManagedId>

Specified by:

clone in class LongMapWrapperImpl<E extends ManagedId>

Returns:

copy
